  1. Er - where are the batteries to (a) operate the pumps (b) operate the noise cancelling and (c) amplify the audio; which comes from precisely where?

    And since a person while walking might breathe in 20-30 liters per minute (100 when exercising), the pumps would have to deliver at least 0.5 liters per second even for someone walking around.

    And how often do you have to replace the filters?

    Unless it really is a sophisticated just pre April 1st hoax.

  2. I've posted this before, but Carl Sagan's commentary is worth repeating here. The image is called Pale Blue Dot, and was taken by Voyager 1 from about the same distance Neptune (6 billion km). Although the Earth is clearly blue, it is actually only 0.12 of a pixel in Voyager's camera.

    "From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

    The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

    Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

    The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

    It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known."

  3. My mother's maiden name is Styants, which is pretty unusual (like Samost). Because it is so strange it is easy to trace back. I've got as far as the late 1600's, but its root is the Anglo-Saxon Stigand. In fact the Archbishop of Canterbury in 1066 when William of Normandy invaded was called Stigand. But clergy back then would commonly take a wife or two, and/or other women, so who knows - I might date back to a very naughty Archbishop 960 years ago.

  4. I have a similar problem with my name. I used to say "Spelt like Tom but with an S at the end" until I realized that the vast majority of people haven't read much at all, let alone The Adventures of Tom Sawyer (which we did at school).

    But I've seen so many spellings of my name. Sawyer is most common, but I've had Saunders, Saywers, Swayers and just about every variant under the sun.

  5. From the link above it looks like Maersk isn't the only shipping outfit to pull out. It might be the biggest though by a decent margin.

    Nestle's position is totally untenable. That it is "only" supplying  "essential" items like baby formula and pet food to Russia misses massively the point that a number of Ukrainian cities are under siege, the population is starving, and have had no power, food or potable water for weeks. And they are having seven kinds of shit bombed out of them daily.

    Well Mr Ulf Mark Schneider with your $20m salary - how about some essential items for Ukraine? And how about pulling the plug on Russia, like over 400 companies so far?

    Bastard.

  6. Yup - this is the opportunity to apply the rest of the world sanctions on Nestle products.

    Looking at the brand diagram, the only one we regularly buy is KitKat. No longer.

  7. I missed this a couple of days ago courtesy of Covid - but the JWST has reached full optical alignment. The alignment object is a star well within our own galaxy, and you can see the 6-fold diffraction from the hexagonal mirrors. It is only visible because of the extreme brightness of the star.

    But everything else you can see are galaxies - right down to the faintest streaks you can pick out. This image is a tour de force of stunning optics and an astonishingly complex machine.

  8. Good on Schwarzenegger. I really hope it makes some difference, but most information channels have been shut down in Russia to make sure that the Russian citizens have no access to anything remotely true.
